Can anyone help my triathlon mate? he has a problem with his Zipp Aero wheels. Both need rebuilt, all the nipples need replaced as they are brittle and a couple have broken. He needs them fixed by Thursday 12 June, as he heading off to Euro Tri Champs on Friday. He's tried a few of the local bike shops but they all seem very busy. Please contact John Soutar directly on his mobile : 07773 376341 if you can help. Thanks.
